How does this filter affect daily driving and throttle response?

The High-Flow media is tuned to allow more air into the intake without sacrificing filtration, which can help engines breathe easier under load and improve throttle response. Gains depend on vehicle, tune, and conditions, but many owners notice crisper acceleration and more consistent engine performance after installation.

• Engineered media increases airflow up to 50% in some applications
• Multi-layer cotton gauze traps contaminants while permitting higher flow
• Pre-oiled and ready to install for immediate performance effect
